PUMP FOR RECEPT'ACLES.

Specification of Letters Patent.

Patented Sept. 30, 1919.

hoga and State of Ohio, have invented a cer- 1 tam new and useful Improvement in Pumps for Receptacles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to devices for dispensing liquids, and more; particularly to pumps which are so constructed as to enable them to be conveniently applied to barrels or similar receptacles for the purpose of removing the contents therefrom.

While the invention is capable of use in connection with other receptacles and for the purpose of dispensing other liquids, it is particularly well adapted for dispensing grease from barrels, and in measured quantitles; and it is the general object of the invention to provide a device of the character referred to which is capable of being eonveniently and quickly applied to and removed from a barrel or like receptacle. A further object of the invention is to provide a device of this character which is sim ple of construction, comparatively inexpensive of production, 'and which will of ficiently perform the dispensing operation, particularly in connection with the handling of viscous substances, such as grease. F'urther and more limited objects of the invention will appear in the detailed description embodied in the specification.

In the drawings forming part hereof, Figure 1 represents a vertical sectional view through a barrel having applied thereto a device constructed in accordance with my invention, said device being shown in eleva tion; Fig. 2 a central vertical section through the said device, corresponding to the line 22 of Fig. 1; Fig. 8 an enlarged sectional detail corresponding to the line 33 of Fig. 2; and Fig. 4E a similar detail corresponding to line 4l--fl of Fig. 2.

Describing the various parts illustrated by means of reference characters, 1 denotes a receptacle, shown as a barrel having a lower head 2 and an upper head 3. The last mentioned head is provided with an aperture 1 for the reception of certain parts of the pump structure which are to be mounted "within the barrel.

On top of the upper head 3 is a support ing base comprising an elongated plate 5 having a disk portion 6 adapted to cover the aperture 4, the plate being secured to the top of the barrel, as by means of screws 7 The plate extends from the central portion of the barrel toward the chime 8, where it is provided with a pair of upwardly extending lugs 9 between the upper ends of which is pivoted one end of the pump handle lever 10, the pivotal connection being indicated at 11. The parts 5, 6 and 9 may be made as a casting and the disk 6 is provided with a pair of upwardly extending hollow projections or bosses 12 and 13, each projection being provided with a set screw, one of which is indicated at 14;. The central portion of the disk 6 is provided with an aperture 6*, intermediate the projections 12 and 13 for a purpose to be described hereinafter.

The pump which is shown herein as em ployed in conjunction with the foregoing parts will now be described. 15 denotes a cap member, which may be conveniently made as a casting comprising a central plate 16 having a depending circular skirt or flange 17 and hollow lugs 18 and 19 on opposite sides of such central plate. When the pump is assembled, these lugs and the openings therethrough will aline respectively with the projections 12 and 13 and the openings therethrough. Each lug 18, 19 is provided with a set screw, one of which is indicated at 19.

Beneath the ca member 15 is a casing member 20, which may also be formed as a casting, said casing member having in the bottom wall 21 thereof an inlet opening 22 controlled by an inwardly opening valve 23 pivoted at one side of said opening 22, as by means of a rod 24 extending through a pivot lug 25 on the valve and mounted in the walls of the casing member. Above the bottom plate 21 is a chamber 26. The top of the chamber is provided with a cover portion 27 provided with cylindrical seats 28 and 29 alining respectively with the aperture through the lug 19 and with the downwardly extending circular flange 17 Both of the seats 28 and 29 are located above the chamber 26, the seat 29 being directly above the aperture 22 and valve 23. At one side of the chamber 26, the casing member 20 is provided with an extension 30 having a cylindrical seat 31 in alinement with the aperture through the lug 18 thereabove. From Within this cylinder is the piston 34. the

operating or plunger rod 35 for which extends through the apertures 16, 4 and 15, the

upper end of the rod being secured to a connecting member 36 which is slidably mount ed upon a guide rod 37 extending from above the head 3 through the hollow. projections 12 and 18, with its lower end secured within the seat 31. A delivery pipe 38 extends through the hollow projections 13 and 19 and is secured at its lower end within the seat 28. By means of the set screws 14: and 19 the guide rod 37 and the delivery pipe 38 may be secured firmly to the disk 6 and the cap member 15, the securing means also serving to anchor the pump proper within the barrel. The deliverypipe 38 is shown as provided withan elbow 39 from which there extends a delivery connection 40.

@The connection 36 is provided with a slot 4 1, located between the top and bottom thereof and the lateral portions cooperating with the rods 35 and 37. The top and bottom portions of the slot walls are rounded, as shown at a2, whereby the handle lever 10 may slide along such walls without binding during the pumping operation. The connecting member 36 is shown as secured to the plunger 35 b means of set screws 43.

The pump assembly comprising the parts 5 4?) inclusive may be applied toa barrel with the parts arranged as shown herein, the plate 5 and the connecting member 36 being adjustable whereby the assembly may be applied to barrels of varying depth.

. With the parts constructed and arranged as described, it is believed that the opera- 7 tion will be readily understood. On the lift ing stroke of the handle lever 10 the piston 34 is elevated, thereby drawing in the grease or other material through the valve 23 until the cylinder 33 is filled. By depressing the handle lever the valve 23 will be closed and an amount of grease or other liquid equal to the contents of the cylinder will be expelled through the pipe 38, the plunger rod 35 and the handle lever being maintained inoperative relation to the other parts of thepump bymeans of the sliding connecting member 36 traveling upon the rod 37 I Through theconstruction described, the v ariousparts of the pump are rigidly supportedin position; the pump operates efliciently for the purposesfor which it is designed and the construction, while markedl y eflicient, comprises a minimum number of parts.

It will be noted that the cap member for the cylinder 33 is detachably secured upon the cylinder through the delivery pipe 38 and the rod 37 being slidably mounted upon said rod and pipe; also that the pipe 38 and rod 37 are secured to the plate 5, thereby anchoring the pump within the barrel and preferably with the feet 32 bearing against the lower head. The plate 5 supports not only the pipe 38and rod 37, but also supports the plunger operating means and provides aguide through which the plunger rod may reciprocate.
